After six years of investigation, the King County Sheriff’s office has made an arrest in connection of a 27-year old woman who was found dead in the trunk of her car in Woodinville.The victim’s former fiancée, Sione P. Lui, 37, was taken into custody about 6 p.m. Friday and charged with second-degree murder, authorities reported.

Elaina Boussiacos died of blunt force trauma and strangulation, and was found on February 9, 2001 in the parking lot of a Woodinville, Washington fitness club.

Sheriff’s detectives said the case was solved in part by DNA, contradictory statements made by the suspect, and “tenacious and extraordinary police work”.

“Our detectives have worked this case for over five years, along with their other robbery, homicide and assault cases,” said Sheriff Sue Rahr. “Unfortunately we don’t have the resources to regularly work all of our cold cases. There are many more homicide cases we believe could be solved if we had more detectives,” she said.

According to detectives, Boussiacos and Lui where living together and engaged to be married at the time of the murder, but the victim told family and friends she was breaking off the engagement when she caught Lui having an affair.

The day she disappeared, the victim had plane tickets to visit her mother in California.Her body was discovered days later when the owner of the fitness club called to report the vehicle abandoned.

Boussiacos was found in the locked trunk, detectives said, and it appeared she had been dressed by someone else.The shoes were tied in bows in an unusual manner, and Lui’sDNA was found on the shoelaces.In addition, her bra was not worn, but stuffed inside her shirt.

A bloodhound brought to the fitness club parking lot immediately picked up a scent and led the handler and detectives about a mile directly to the couple’s door.
